General description

Chloroacetic acid belongs to the class of haloacetic acid compounds.
Chloroacetic acid is the degradation product of the herbicide, chloroacetanilide.

Application

Chloroacetic acid may be used as an analytical reference standard for the analysis of chloroacetic acid in:
  • Natural waters by ion chromatography-electrospray ionization-tandem mass spectrometry (IC-ESI-MS/MS).
  • Bottled water, swimming pool water, and both source water and drinking water from a drinking water facility by high performance IC-ESI-MS/MS with multiple reaction monitoring (MRM) detection.
  • Tap water by gas chromatography-mass spectrometry (GC-MS).
  • Drinking water by GC coupled to halogen-specific detector equipped with MS operating under the electron ionization mode.

Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
